尾梁

The shape of a virtual tail beam is given by the deflection curve of a fixed-ends beam .

它假定每个车辆有一虚拟的尾梁，而虚拟尾梁的形状用固支梁挠度曲线来表示，进而得到了一种推广了的固支梁挠度曲线模型。

Supporting type is suggested to be developed into 3-prop to improve adaptability besides 2-prop and 4-prop. The difference of caving difficulty degree of coal seam is the base of caving coal method at high, medium and low position. Caving with small step and open caving flashboard used widely not only cause serious mixture of coal and rock but also hinder the improvement of top coal recovery. So we suggest caving with large step or closing caving door. Four-bar-mechanism of hydraulic support restricts development of new style caving powered support. Stabilization framework of expansion link and all-shield caving tail beam at high, medium and low position are introduced here.

支架支护型式，除了两柱、四柱以外，建议开发三柱支架以改善适应性；煤层冒放性的差异，是高位、中位和低位放煤方法存在和使用的依据；目前广泛采用的小步距放煤和开放式放煤插板不仅造成严重混矸漏矸，也妨碍顶煤回收率的进一步提高，建议采用大步距放煤和可关闭放煤口；液压支架四连杆稳定机构，制约了新型放顶煤液压支架的开发，介绍了液压支架伸缩杆稳定机构及全掩护拖移高位、中位和低位放煤尾梁。

The vessel's upper deck camber is to be of knuckled line, and the knuckle camber is 150mm; poop deck has parabola camber of 150mm; compass deck is to have a parabola camber of 150 (half width of 12m).

本船上甲板梁拱为折角线，折角梁拱为150mm；首、尾楼甲板为抛物线梁拱150mm；罗经甲板为抛物线梁拱150（半宽12m时）。

The key of settling the difficulties of supporting and caving is to develop and adopt the new style hydraulic caving supports with tail beam of expansion link combined by above 2 new technologies.

全面解决支护和冒放等难题，关键在于开发和采用由上述两项新技术结合而成的新型放顶煤液压支架－伸缩杆尾梁放顶煤液压支架。

The truncated normal distribution is used to describe the bounded random variables, such as the hydrostatic load, thickness of web and thickness of flange.

采用截尾正态分布主梁可靠度分析中的随机变量（闸门水荷载及主梁的腹板及翼缘的厚度等）。
